Description
Technical field
The utility model relates to a kind of closed container pressure and regulates correlative technology field, specifically a kind of float-type exhaust apparatus be applicable in closed container with pressure.And be applicable to the closed container product with pressure that all splendid attire media are liquid.
Background technology
Current Pressure Vessel series products relates to numerous areas, and being widely used in the departments such as electric power, chemical industry, oil, machinery, metallurgy, nuclear energy, Aeronautics and Astronautics, is indispensable nucleus equipment in production run.Emptying for the gas in container container gas-liquid space that makes is become fluid space, substantially increase the security of operation, decrease the possibility occurring accident, avoid the danger because container gas-liquid mixed produces, decrease the corrosion that gas-liquid space is caused to container simultaneously, improve security and the serviceable life of the container of gas-liquid space motion.Particularly in closed container manufacture, maintenance, when transformation need carry out hydro-test, cannot by emptying for gas in container maybe can gas in container is the emptying but situation that input ratio is larger, this device can convenient, fast realization gas in container is emptying.
Such as, in container products, most pressure vessel and equipment is equipped with the related accessories such as manhole, exhausr port, for maintenance and use brings convenience, but highly professional, difficulty strengthens in the fabrication process.Also have some containers due to design parameter restriction can not designing and arranging gas port, this brings difficulty just to product testing and detection.The container that great majority manufacture completion all should carry out withstand voltage test by design document regulation, wherein hydro-test is its main test method, after hydro-test specifically refers to that container is made or overhauled, for checking whether container has seepage or abnormal deformation, to find the latent defect in vessel fabrication or maintenance; The macro strength of examination container, ensures the necessary load-bearing capacity of safe operation under design pressure, and the pressure test being medium with liquid (being generally water) of carrying out.
In the process of carrying out hydro-test, the first step is gas in test chamber should emptying be full of liquid, in process of the test, container should be kept to observe the drying on surface.Therefore emptying gas in container is for test, and whether success is most important.Begin to rehearse above prior art adopts mostly gas port, or go deep into the mode of a gas outlet, and the former increases manufacture difficulty and risk of leakage, and the latter can not be emptied completely gas.In addition, some container does not allow at container upper opening, or do not allow gas to enter.This device effectively can solve the problem of this type of container hydro-test exhaust process.
For solving this difficult problem, thorough emptying gas in container, increases work efficiency, reduce corrosion simultaneously, improve security and serviceable life, need the device of gas in a kind of special emptying receptacles, and there is not been reported can to realize the float-type exhaust apparatus of above-mentioned purpose at present.This device has a extensive future, be applicable to multiple occasion and operating environment, is easy to operation.
Utility model content
The purpose of this utility model is for container emptying gas difficulty in prior art, maybe needs the present situation of increase perforate exhaust and provides a kind of float-type exhaust apparatus be applicable in closed container with pressure, thoroughly can solve the problem of emptying gas.
The purpose of this utility model is achieved through the following technical solutions: a kind of float-type exhaust apparatus, it includes pipe connecting flange, pad, suppress blind plate, tensimeter, it is characterized in that: described pipe connecting flange, pad and suppress blind plate is installed in container to be tested flange-interface place by fastening bolt; Blind plate is provided with one and is tightly connected place suppressing, sealing junction is connected with the resistance to compression flexible pipe of a band float in container to be tested, and sealing junction is connected with vent valve by metal tube outside container to be tested; Also be provided with a test inlet suppressing on blind plate, be also connected with the manometric water intaking valve of band outward at test inlet.
Described metal tube is the external metal winding pipe of its height higher than container head to be tested.
Float bottom is added with weight, and weight vertical line is coaxial with float upper end air flue, ensures that upper airways is in float summit all the time.
Be welded and fixed connection resistance to compression flexible pipe by float, enter from pipe connecting flange, be sealedly attached to the outer blind plate of pipe connecting flange, resistance to compression flexible pipe TOE, add wound gasket to be connected with blind plate sealing, external metal winding pipe is communicated with tensimeter, inner due to buoyancy, float rises to container top, during injection test liquid, arrival top is completely only had to be full of container, i.e. vent gas, the flexible pipe that float connects just can enter liquid, reaches the object of emptying gas.
For vertical vessel hydro-test, generally need be horizontally-arranged by it when suppressing, the metal resistance to compression flexible pipe of float will be connected with, stretch in housing by the pipe connecting flange on housing, resistance to compression hose end with suppress blind plate sealing and be connected, flexible pipe is connected with external metal winding pipe through suppressing blind plate, and metal winding pipe is welded on to be suppressed on blind plate, and the other end of external metal winding pipe is connected with vent valve.When housing injection test liquid, float rises to case top due to buoyancy, after liquid is full of housing completely, represent the whole emptying of gas, when test chamber wall metal temperature and fluid temperature close to time, slowly can boost to design pressure, confirm the follow-up test pressure being depressed into regulation of continuing rising of No leakage, the dwell time is generally no less than 30min; Then be down to design pressure, pressurize enough time checks, during inspection, pressure remains unchanged.In process of the test, container No leakage, without visible distortion and abnormal noise.Be hydro-test to pass through, container meets design requirement.After hydro-test, liquid should be drained, with pressurized air, inside be dried up.
Design feature of the present utility model:
First for float is fixedly connected with resistance to compression flexible pipe and is connected, the requirement of resistance to compression flexible pipe can bear the pressure born needed for container to be tested, and the flexible pipe other end adds screw thread and suppresses blind plate sealing and be connected.
The utility model has following beneficial effect and advantage:
1, utilize the buoyancy of float, the liquid level of test(ing) liquid can be made thoroughly to reach container head, realize the object of emptying gas.
2, the flexible pipe of this structure is flexible, and handling are easily, easy to operate, saves time, laborsaving, the features such as labour intensity is low, and range of application is wide.
